Title: Backwash type regenerator for diesel particulate filter
Inventor: SHIMODA MASATOSHI
IPC: F01N3/023
Filed: 1990-10-30
Abstract: PURPOSE:To uniformize completely a large quantity of backwash air flow so that it can keep at an appropriate flow rate by arranging a diffuser downstream of a diesel particulate filter, and arranging a backwash air nozzle at an end part positioned downstream of this diffuser. CONSTITUTION:While a diesel engine is operated, and when a filter 13 to filtrate exhaust gas from the engine has reached a regeneration time and its regeneration has to be carried out, a valve 17 is closed when the engine is stopped, on the one hand, and a valve 20 is opened, on the other, and compressive air in an air reservoir 19 is injected into an opening 16b of a diffuser 16 through an air nozzle 8. Though this injection air is flown forcibly into a circular cone part 12b of a housing 12, in this case, since air surrounding the opening 16b of the diffuser 16 is absorbed into the diffuser 16 by means of the injection air from the air nozzle 8, the volume of the injection air becomes large, and a flow speed distribution of backwash air in the radial direction of the circular cone part 12b can be also uniformized. Thereby, particulates scavenged by means of the filter 13 can be blown out uniformly into an upstream space 15.

Abstract: PURPOSE: To make the indoor temperature uniform due to vigorous convection of the air, to suppress the unnecessary combustion and to delete the running cost by setting the number of revolutions of a warm air fan motor to the value higher than the normal value when a predetermined time is elapsed after the room temperature reaches the set temperature. CONSTITUTION: A room temperature is set by the temperature set switch 13 of an operation board 5. When the switch 11 is operated, it is recognized by a microcomputer 15 to drive a burner 7, thereby starting the combustion operation. Simultaneously, the microcomputer 15 controls the combustion amount of the burner 7 and the air flow rate of a warm water fan motor 9 based on the detected input of a room temperature sensor 14, and continues the combustion operation toward the set temperature. When the room temperature is gradually raised to reach the set temperature, a heater is weakly operated for the combustion to stabilize the room temperature. In this case, after the predetermined time is elapsed, the number of the revolutions of the motor 9 is set to the value higher than the normal value.  Thus, the convection of the air is vigorously set to make the room temperature uniform, the unnecessary combustion is suppressed, and the running cost is reduced.
